Dendrometer for making measurements of plant organs has a sensor, and sensor frame with flexible mountings acting to hold the frame to at least one sensor contact point so that the it does not move away from the measurement object
Dendrometer for continuous measurement of diameter changes in plant organs has a sensor that is attached to the measurement object with the help of a frame so that it has two contact points on the object. The dendrometer also has a mounting that forms a mechanical connection between at least one of the two contact points and the measurement object and serves to prevent movement of the frame away from the measurement object.
